ARM11 Processor Family

The ARM11™ processor family provides the engine that powers many smartphones in production today and is also widely used in consumer, home, and embedded applications. It delivers extreme low power and a range of performance from 350 MHz in small area designs up to 1 GHz in speed-optimized designs in 45 and 65 nm. ARM11 processor software is compatible with all previous generations of ARM processors, and introduces 32-bit SIMD for media processing, physically tagged caches to improve OS context switch performance, TrustZone for hardware-enforced security, and tightly coupled memories for real-time applications.

In the ARM11 processor family, only the ARM1176JZ(F)-S processor has ARM TrustZone™ technology. TrustZone technology provides support within the CPU and platform architecture for building the trusted computing environments required to enable protection of critical system functions from downloaded applications, copyright protection of downloaded media, safe over-the-air system upgrades.

Scalable Multicore performance with ARM11 MPCore Processor

The ARM11 MPCore synthesizable multiprocessor, based on the ARM11 microarchitecture, can be configured to contain between one and four processors delivering up to 2600 Dhrystone MIPS of performance.

These processors also feature optional parity protection for caches and Tightly Coupled Memories (TCM), and non-maskable interrupts, making them ideal for embedded control applications where high reliability or high availability are paramount.

The ARM1156T2-S processors feature an enhanced Memory Protection Unit (MPU) and offer an ideal upgrade path for embedded control applications currently using ARM946E-S, ARM966E-S or older 16-bit processors.

All ARM11 family processors are delivered as ARM-Synopsys Reference Methodology compliant deliverables which significantly reduce the time to generate a specific technology implementation of the core and to generate a complete set of industry standard views and models.

Cortex Alternative

The Cortex™-A5 processor is a related follow-on product to the ARM1176. The Cortex-A5 processor offers similar speed to ARM11™ processors, at lower power and smaller die area, with the ARMv7 benefits of NEON™, and TrustZone®, as well as a more advanced AMBA® AXI™ bus. Cutting edge new SoC designs for are starting now based on the ARM Cortex-A5 processor, however some SoC designs are still starting with ARM1176 processor where cost and minimal risk are important considerations.

System IP

The ARM1176 processor is commonly integrated with many other IP blocks to optimize the SoC for performance, power, and security.

System IP components are essential for building complex system on chips and by utilizing System IP components developers can significantly reduce development and validation cycles, saving cost and reducing time to market.

The Mali™ family of products combine to provide the complete graphics stack for all embedded graphics needs, enabling device manufacturers and content developers to deliver the highest quality, cutting edge graphics solutions across the broadest range of consumer devices.
